In this paper we study synchronization properties of the oscillators with
chaotic phases. First, we construct a rather abstract model, where phase chaos and
synchronizing interactions are separated in time (Section ). Namely, the process
consists of two epochs: in one epoch phase oscillators interact according
to the Kuramoto global coupling scheme, and in another epoch the phases undergo
a chaotic Bernoulli map. This model demonstrates, for certain values of parameters,
a bistability between a desynchronized and a synchronized states. In Section 
we consider coupled autonomous oscillators with chaotic phases, constructed
by S. P. Kuznetsov and the author in [1]}. This
system demonstrates a rather reach behavior with asynchronous, completely
synchronous, and complex partially synchronous states.
